specifications generally reference the rising edge of the clock, these AC timing diagrams also apply when
the falling edge is the active edge.

Notes:
1. Output specifications are measured from the 50% level of the rising edge of CLKIN to the 50% level of the signal.
2. The symbols used for timing specifications follow the pattern of t
